Autologous blood injections (ABI) harness the healing properties of blood to naturally accelerate healing of tendon injuries/degeneration and osteoarthritis, without subjecting the body to significant risk. The tendons are relatively avascular, the process of healing in a tendon tear is often delayed. Repetitive injury at the same site leads to poor healing and myxoid degeneration within the tendon. While injections of steroid and local anaesthetic into the tendon along with a rehabilitation program are a good first line of management, various studies have confirmed that injecting autologous blood under imaging guidance into the tendons stimulates a healing response. Unlike the anti-inflammatory effect of steroids, blood initiates an inflammatory response within the tendon leading to accumulation of various growth factors which in turn leads to angiogenesis and repair of the tendon.
